Seems fine to me. Not sure if its worth chasing it when the board is paired and at turn you could be already dead.

River bet sizing depends on what you think villain has, if you're confident he has a T or an A and is def felting those then shove for value, if you're trying to squeeze value out of weaker hands then bet like $8
